Objectives: The fight against doping is a challenging task. Doping is a complicated phenomenon, thus the purpose of this study was to investigate relationships between doping attitudes and other psychological factors. Methods: Fiftyfive competitive elite male wrestlers (Age: 25.63 ± 3.14 yrs; Height: 173.46 ± 4.27cm) from the Kermanshah and Kurdistan states of Iran were participants in this study. All subjects completed the Performance Enhancement Attitude Scale (PEAS), Sport Multidimensional Perfectionism Scale (MPS), Form V of the Sensation Seeking Scale, Task and Ego Orientation in Sport, Trait Sport Confidence Inventory and the Doping Use Belief questionnaires. Results: Pearson's correlation coefficients showed a significant positive correlation between the PEAS with Doping belief (r=.582, p<.01), Disinhibition (r=.388, p<.01), Perceived Coach Pressure (r=.329, p<.05) and Concern over Mistakes (r=.298, p<.05) and had significant negative correlation with Task orientation in Sport (r=-.363, p<.01). Multiple regression showed the combination of psychological factors significantly contributing to the prediction of Doping Attitude; F (4, 43) = 6.84, p < .001, R 2 = .33. Conclusion: It is obvious that the most effective approach in the fight against doping is prevention, thus the identification of athletes who score high in the personal characteristics of perfectionism, sensation seeking and goal orientation in sport could be helpful information for coaches and team physicians, in order to detect, monitor and further work with the athletes that may be at higher risk for doping. INTRODUCTIONDoping is one of the undesirable, yet unavoidable consequences of the institutionalized sports. From the competitive athlete's perspective, sport is more than just a game as he or she strives for success and achievements in sport competition. In many sports, wining may lead to gaining many advantages such as money, fame, popularity and social acceptability, things that are pursued by many. It seems that doping behavior is forms and seen as the vicious circle of the constant desire to enhance performance that is developing when athletes progress in their sports career. In this process, some athletes may become more susceptible to doping than others, depending on the combination of their personality and the situation. Therefore, both the individual (personality trait) and systemic factors contributing to doping behavior should be fully investigated in order to underpin effective, targeted anti-doping intervention (2).
